Question

These are two seperate problems..please help if you can. Would
appreciate it.

Show transcribed image textA square wire loop (size L times L) carries current I. Find the magnetic field at the center of the loop. A compass can detect a magnetic field as small as 50 microT. If the size of the loop is 1.0 m times 1.0 m, what is the smallest current that you can detect by placing the compass at the center of the loop? A circular conduction ring of radius R is connected to two exterior straight wires at two ends of a diameter as shown in the figure. The current I splits into unequal portions (as shown) while passing through the ring. What is (direction and magnitude) at the center of the ring?
